[−][src]Trait kas::prelude::Directional

pub trait Directional: Copy + Sized + Debug + 'static {
    type Flipped: Directional;
    fn as_direction(self) -> Direction;

    fn is_vertical(self) -> bool { ... }

    fn is_horizontal(self) -> bool { ... }

    fn is_reversed(self) -> bool { ... }
}

Trait over directional types

This trait has a variable implementation, Direction, and several fixed implementations, Right, Down, Left and Up.

Using a generic <D: Directional> allows compile-time substitution of direction information when parametrised with fixed implementations.

Associated Types

type Flipped: Directional

Direction flipped over diagonal (i.e. Down ↔ Right)

This allows compile-time selection of the flipped direction.
